D4701A Datasheet Upd4701a

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD4701A INCREMENTAL ENCODER.

General Description

The µPD4701A is a counter for an X, Y 2-axis incremental encoder.

When a two-phase encoder signal is input for the X and Y axes, direction discrimination and putation is performed, and count data is output in 8-bit parallel form.

In addition, a 3-contact-point input buffer is incorporated, which is useful for applications which use a pointing device such as a mouse or track-ball.

Key Features

  • X, Y 2-axis incremental encoder counter.
